Question

Define Phase diagram and comment on the relationships among the phases of a single
substance according phase diagram.

Answer 1

Phase changes include vaporization, condensation, melting, freezing, sublimation, and deposition

Explanation:

Definition:

• A Phase diagram is a graphical representation of the physical states of a substance under different conditions of temperature and pressure.
• A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs.
• In addition, two states of the substance coexist in equilibrium on the lines or curves.

The relationship between a Single phase diagram according to the phase diagram is a critical point.

• the point in temperature and pressure on a phase diagram where the liquid and gaseous phases of a substance merge together into a single phase.

• Beyond the temperature of the critical point, the merged single phase is known as a supercritical fluid.
